Due to the continued decline and elimination of serial communication ports in server manufacturing and in an effort to minimize e-waste, APC™ by Schneider Electric will no longer be providing the RJ-45 to serial communication cable with the Smart-UPS™ SMT750, SMT750US, SMT1500RM2U, or SMT1500RMUS models.

Resolution:

For a limited time this serial cable will be made available free of charge by registering at http://serialcable.apc.com
You will need your exact model and serial number available when registering. You can find this information on the back of the UPS, a sticker on the corner of the shipping box, or via the "About" menu on the LCD screen.
